Add custom marshaller for pre-signed URL GET operations

[jencymaryjoseph]

Implements custom marshaller for pre-signed URL GET operations in AWS SDK Java v2.

Motivation and Context

Pre-signed URLs are pre-authenticated URLs that can be used as is. The custom marshaller handles this by performing direct URL marshalling.

Modifications

Added the custom marshaller needed for pre-signed URL Get Object Request processing

Testing

Added unit test suite that validates Range header formats, URL preservation, and error handling for malformed requests. Tests ensure marshaller correctly handles pre-signed URL specifics without breaking authentication signatures.
